The China Compulsory Certification (CCC) is a mandatory certification system implemented by the Chinese government to ensure the safety, electromagnetic compatibility, and energy efficiency of various products, including switching power supplies. It plays a vital role in regulating the market and protecting consumers' interests within China.

The CCC certification for switching power supplies is based on several national standards, such as GB 4943.1, which covers the safety requirements for information technology equipment, including power supplies. This standard emphasizes requirements for electrical insulation, mechanical strength, and protection against electrical hazards. For example, it requires proper grounding of the power supply to ensure that any leakage current can be safely conducted away, reducing the risk of electric shock to users.

In addition to safety, CCC certification also focuses on electromagnetic compatibility. Switching power supplies must comply with GB/T 17625.1 and GB 9254, which regulate electromagnetic emissions and immunity. Similar to CE certification, the CCC certification process for EMC requires manufacturers to control the electromagnetic interference generated by the power supply to prevent interference with other electronic devices and ensure that the power supply can operate stably in a complex electromagnetic environment.

To obtain CCC certification, manufacturers need to submit their products for testing at designated certification institutions. The process includes product type testing, factory quality assurance assessment, and post-certification supervision. Once the product passes all the tests and the factory meets the quality management requirements, the CCC mark can be applied. Without CCC certification, switching power supplies are not allowed to be sold, imported, or used in commercial activities in China, making it an essential requirement for companies aiming to enter the Chinese market.
